A recentpaper by Foxx and Shapiro (1978) used a nonexclusionary timeoutprocedure to reduce inappropriate behaviors in a mentally retarded population. The present study was designed to replicate these findings, to examine the utility o f modifying the basic reinforcement schedule of the original study, and to demonstrate control across settings and maladaptive behaviors using a multiple baseline...

BACKGROUND The split-course schedule of chemo-radiation for anal cancer is controversial. METHODS Eighty-four patients with invasive anal cancer treated with definitive external beam radiotherapy (RT) with a mandatory split of 12 days (52 patients, Montreal, Canada) or without an intended split (32 patients, Zurich, Switzerland) were reviewed. Total RT doses were 52 Gy (Montreal) or 59.4 Gy (...

We investigated associations between personality dimensions assessed via the Five-Factor Model and change in negative mood and confirmation of affective expectations, and the mediating role of perceived vacation-related stress in these associations. The sample consisted of 100 employees participating in their annual planned vacation assessed at entrance and checkout after spending one week at a...

As processor power density increases, thermal and power control becomes critical for packet processing. Network applications feature ON/OFF execution pattern, which causes frequent temperature and power consumption changes in the processor. In this paper, we propose a novel power aware thermal management algorithm, which achieves power saving in multicore processors by employing a vacation sche...

In many industrial situations, machines are subjected to random breakdowns. In this paper, we consider the asynchronous vacation policy for the multi-server machine repair problem with server breakdown and two types of spares. According to this policy, when a certain number of servers become idle at a service completion instant, the servers will take an asynchronous vacation of random length to...

Besides dealing with high workload, being a teacher is challenging with respect to the social context. There is increasing evidence that adverse social job characteristics challenge sleep quality. The current study tests whether restraint sleep quality (defined as worse sleep quality before than during vacation) is related to time-related job stressors, job resources, and social job characteris...

The option of daily hemodialysis (HD) was discussed in November 1998 with a group of 35 HD patients on home or self-care/limited-care HD in a single, freestanding unit. After the meeting, 3 patients on home HD chose to switch to daily HD. The clinical success of the first patient and the immediate followers was one of the main reasons for further extension of this experience. At the time of thi...

A multiple optional vacation policy for the unreliable server batch arrival queueing system with essential and multi optional services under N-policy is investigated. According to vacation policy, the server takes an essential phase of vacation after the completion of service of an individual customer when queue becomes empty. On returning from the vacation, if the server finds the queue empty,...
